Description

Description: The invention relates to a method for measuring the mass distribution along the width of a strip moving along its longitudinal direction, in particular a dough strip. The invention further relates to a weighing device for measuring the mass distribution along the width of one along its longitudinal direction moving belt, in particular a Teigbandes, according to the preamble of claim 7.

In the prior art dough bands are set at Teigbandanlagen means of sizing or other rolls to a predetermined dough thickness. Particular attention is paid to ensuring that the sizing rolls or other rolls are equidistant from one another to achieve a homogeneous dough sheet thickness. Furthermore, in the prior art, the weight of already cut dough pieces is taken up by means of weighing units and underweight dough pieces are sorted out, since underweight dough pieces must not be sold. Based on the measured weight of the finished dough pieces, the cutting device is then readjusted to minimize a committee.

From EP 2693174 A1 (RADIE B V) of 05 February 2014, an apparatus and a method for weighing one or more bands known, wherein the bands move along the longitudinal direction of a conveyor belt. Based on the measurement data of the juxtaposed load cells, one or more cutting devices can be controlled.

In US 4631021 A (HAYASHI TORAHIKO) of December 23, 1986, a weighing device is disclosed in which the rollers of the weighing device are located between two conveyor belts and the belt speed and the measurement data of the weighing device are used for the control of calibration rollers, to compress or stretch the mass flow.

Furthermore, EP 2405244 A1 (BIZERBA GMBH & CO. KG) of 11 January 2012 discloses a weighing device which is suitable for use as a multi-track scale for the dynamic weighing of belts along the longitudinal direction of a conveyor belt.

Disadvantage of the previous weighing devices and methods is that the irregularities in density and weight, for example, too high or too low weight, the dough are not detectable. Thus, a number of pieces of dough is always produced incorrectly before readjustment can take place within a dough sheeting, cutting equipment or rolling mills. Likewise, too much weight of the dough pieces is undesirable because, while they can be sold, the deviation causes a waste of dough and thus an increase in cost.

The object of the invention is therefore to reduce the committee of Teigbandanlagen.

This object is solved by the characterizing features of claim 1. It is provided that by means of at least two load cells, which are arranged at a distance from one another with respect to the width of the strip, the weight of at least two defined sections with defined by the distances of the load cells width is detected, the mass of the sections of the tape under consideration the distance of the load cells relative to one another, the position of the load cells along the width of the belt, the belt speed and the measured values of the weight of the parts detected by the load cells, in particular over a defined period of time.

By measuring and detecting the mass distribution of the dough strand or Teigbandes errors and deviations of the mass, density and / or weight can be determined at one or more points of the dough strand. Thus, irregularities in the dough can be determined even before a cutting process or a further processing of the dough.

Furthermore, as a countermeasure in the case of an adjustable rolling mill, for example, a one-sided thickness adaptation or skewing of the rolls can be predetermined in order to counteract a general difference in thickness or density difference and thus weight deviations.

Furthermore, it is an object of the invention to provide a weighing device with the help of the committee in the production of dough pieces and dough bands can be reduced.

Further advantages and embodiments of the invention will become apparent from the description and the accompanying drawings.

The invention is illustrated schematically in the following on the basis of particularly advantageous, but not limiting, exemplary embodiments in the drawings and will be described by way of example with reference to the drawings, in which: Figure 1 shows an isometric sectional view of the weighing device.

Fig. 2 shows a sectional view of another embodiment of the weighing device.

Fig. 3 shows a side view of the weighing device according to FIG. 2 in section.

Fig. 4 shows a detailed view of an embodiment of the load cell.

Fig. 5 shows an alternative embodiment of the load cell with sliding block.

In Fig. 1, an embodiment of the weighing device 10 according to the invention is shown in an isometric view. The weighing device 10 comprises two conveyor belts 4a, 4b which convey a dough strip placed thereon, for example within a dough sheet plant. The conveyor belts 4a, 4b have the same direction of rotation and transport on the conveyor belts 4a, 4b applied dough sheet along the longitudinal direction of the dough sheet. Furthermore, the weighing device 10 has sixty-four weighing cells 2 arranged at a distance from each other with respect to the width of the conveyor belts 4a, 4b and dough sheet, respectively. The load cells 2 are uniformly distributed over the width or perpendicular or transversely to the running direction of the conveyor belts 4a, 4b and are arranged in alignment next to each other. The weighing cells 2 project beyond the plane of the two conveyor belts 4a, 4b and are each loaded with the weight of individual sections of the dough strip. In this case, the weighing cells 2 measure the weight of the respective section of the dough strip and forward the detected measured values to an evaluation unit 7. Each load cell 2 thus measures the weight of a defined portion of the dough band. The evaluation unit 7 then determines the mass of the sections or the change in the mass of the sections taking into account the measured values recorded by the weighing cells 2 and, for example, compares the masses of the sections with one another and / or creates a model of the dough strip based on mass distribution across the width of the dough strip ,

2, a further embodiment of the weighing device 10 according to the invention is shown in a sectional view. The section runs perpendicularly through the transport plane of the conveyor belts 4a, 4b and in the longitudinal direction of a dough belt which is placed on the conveyor belts 4a, 4b and moved by the conveyor belts 4a, 4b in its longitudinal direction. The weighing device 10 has two conveyor belts 4a, 4b, which are guided circumferentially in each case via deflection rollers 11, in this view in the clockwise direction. The weighing device 10 further comprises a number of weighing cells 2.

FIG. 4 shows a detailed view of a load cell 2 used in the embodiment of FIGS. 2 and 3. The load cell 2 is designed as a bending web weighing cell and in each case has an elongated cuboid shape. The load cell 2 is connected on one side via a roller holder 12 with the axes of a transport roller 3. At the opposite end of the roller holder 12 of the load cell 2, the load cell 2 is screwed to an intermediate piece 13.

Fig. 3 shows a side view of the embodiment shown in Fig. 2 of the weighing device 10 according to the invention in section with the same cut as in Fig. 2. The weighing device 10 comprises two conveyor belts 4a, 4b, which are arranged one behind the other in the transport direction of the dough strip , The weighing cells 2 and the transport rollers 3 are arranged in the running direction of the two conveyor belts 4a, 4b between them. Upon transfer of a lying on the conveyor belts 4a, 4b Teigbandes of the conveyor belt 4a on the other conveyor belt 4b, the transport rollers 3 and thus the load cells 2 are subjected to the weight of the dough strip. The respective load cell 2 is thus subjected to the weight of a portion of the dough strip. With uniform spacing of the transport rollers 3 and the Wiegzellen 2 with each other each weighing cell 2 is acted upon by the weight of an equal portion of the dough strip. The width of the sections corresponds to the distance between the load cells 2 and transport rollers 3 to each other. If, for example, the dough strip is 800 mm wide and a number of sixty transport rollers 3 are distributed uniformly along the width of the conveyor belts 4a, 4b, then each section weighing on the load cells 2 is approximately 13 mm wide, if the width of the conveyor belts 4a, 4b is the width of the dough strip equivalent. In order to achieve a different width of the respectively measured sections, the transport rollers 3 or the weighing cells 2 can also be arranged at a different distance in accordance with the requirements. With the appropriate selection of the distance between the weighing cells 2, the weight of sections with a defined width is always provided for the evaluation.

As shown in Fig. 2 and Fig. 3, the load cells 2 are bolted to the spacer 13 on a frame 6 of the device 10. The transport rollers 3 project beyond the plane of the conveyor belts 4a, 4b. By a by means of the conveyor belts 4a, 4b along the longitudinal direction moved Teigband the transport rollers 3 are each subjected to the weight of a section, while the dough is moved by the conveyor belts 4a, 4b on the transport rollers 3. By acting on the transport rollers 3 and thus on the load cells 2 weight of the sections, the transport rollers 3 are applied to the surface of the dough strip. This weighting is then detected by the weighing cells 2, for example by measuring a minimum displacement of the end of the respective weighing cell 2 connected to the transport roller 3. Respectively adjacent weighing cells 2 are arranged rotated on the frame 6 of the device 10, so that the transport rollers 3 connected to the respective weighing cells 2 are arranged in alignment next to each other, but the ends with which the weighing cells 2 are connected to the intermediate pieces 13, respectively offset or to Turn 180 ° or point away from each other. This causes a compact design and it can narrower distances of the transport rollers 3 realized or smaller portions of a laid on the conveyor belts 4a, 4b Teigbandes be measured and the accuracy or resolution of the measured mass distribution can be increased.

Alternatively, thirty-two, sixteen or any other number of weighing cells 2 may be provided. The weighing cells 2 may alternatively be designed, for example, as shear load weighing cells, shear beam weighing cells or traction weighing cells, or as other weighing cells or load cells known from the prior art.

The weighing cells 2 or the transport rollers 3 can, as shown in FIGS. 2 and 3, be distributed uniformly over the width of the conveyor belts 4a, 4b or also at different distances from each other. Alternatively, only one conveyor belt 4 or no conveyor belt can be provided if the weighing device 10 is arranged, for example, between two processing stations with their own conveyor belts in their transfer area.

Alternatively, the load cell 2 may also be connected as shown in Fig. 5 with a rigid or movable sliding support 16 or other suitable transfer elements via an intermediate piece or directly.

In the following, an inventive advantageous method for detecting the weight of the sections or the mass distribution along the width of a dough strip is explained: In order to detect the mass distribution along the width of a dough strip, the dough strip according to the invention along its longitudinal direction, ie moved along the endless length of the dough sheet. The dough sheet has a predetermined set width impressed by rollers or other shaping devices. By means of at least two weighing cells 2 with a different arrangement across the width of the dough strip, as shown for example in the embodiments of FIGS. 1 to 3, the weight of a plurality of defined sections of the strip of defined width and corresponding to the number of weighing cells 2 can Length to be recorded.

The mass of the portions of the dough sheet can then be determined taking into account the distance of the weighing cells 2 to each other, the position of the weighing cells 2 to the dough sheet, the belt speed and the measured values of the weight of the portions detected by the weighing cells 2 over a defined period of time.

For example, the mass distribution of a dough sheet having a width of 600 mm is detected by means of sixty weighing cells 2 by comparing the measured values detected by the weighing cells 2 with each other for the same time. Each piece of dough sheet measured by weighing cells 2 is thus 10mm wide. By mapping the weight of the sections according to their arrangement over the width of the dough strip or comparison of the individual detected mass values of the weighing cells 2, the mass distribution can be detected by an evaluation unit 7 along the width of the dough strip. The detected mass of the cuts can then be compared with a desired value or with the mass of the other cuts and so irregularities in the mass distribution along the width of the entire dough sheet can be detected.

Furthermore, for example, the measured values of the weighing cells 2 can be integrated over a defined time range and thus mass changes along the width and / or length of the dough sheet and or deviations in the production process of the dough sheet can be determined.

Furthermore, the mass flow of a dough belt 2 transported over the weighing cells 2 or a plurality of dough belts or dough strands guided in parallel over a respective part of the weighing cells 2 can advantageously be determined. By means of the belt speed of the dough belt moved over the weighing cells 2 and the masses moving over the weighing cells 2, a mass flow is calculated by integrating the measured values obtained from the weighing cells 2.

An application of the method and the device according to the invention provides that they are arranged or used within a Teigbandanlage. For example, the weighing device may include a cutting unit, e.g. a longitudinal cutting unit, follow within the Teigbandanlage that cuts the dough in subbands with equal mass per meter length or pieces of the same mass. The cutting width of the cutting unit can then be predetermined by the determined mass distribution of the strip so that the endless subbands cut by the cutting device along the longitudinal direction of the strip have the same mass per centimeter of length of the subband. About the transport speed and the timewise mass distribution of the dough strip and the arrangement of the separating device relative to the weighing device 10 can always be produced time-dependent always dough pieces or sub-bands with the same mass by adjusting the cutter. Flierdurch is already anticipated acting on the cuts of the cutting device and always produced committee-free and weight accurate. For example, in the event that a dough area to be cut becomes too heavy, the cutting width for this

Reduced range and thus the weight can be adjusted.

Since this can have an effect on the cutting width adjacent sections, the cutting width of the other sections can be advantageously adjusted according to the adjustment of the width of a section. As a further measure, alternatively, the longitudinal section of the dough strip or, the sub-bands can be adjusted.

Another application provides that the weighing device 10 are readjusted within a Teigbandanlage one or more adjustable rollers. The setting of the rollers is variable by a control unit taking into account the determined weight distribution along the width of the belt.

By recording the mass distribution of the dough strip, for example, continuous errors can be detected at one or more points of the dough strand. As a countermeasure can be given in a Teigbandanlage with adjustable rolling a one-sided thickness adjustment or misalignment of the rollers to counteract a difference in thickness or the deviation of the mass distribution of the dough strip or individual portions of the dough strip. If e.g. tends to have the right Teigbandseite more weight than the left Teigbandseite, this can be corrected by a deliberate misalignment of the adjustable Kalibrierwalze or other rollers. Likewise, alternatively, the use of multiple adjustable sizing one after another, the correction can be performed gradually refined and thus the dough is evenly shaped.

Depending on the arrangement of the weighing device 10, a pre-correction in the rolling mill via speed adjustment or gap adjustment can take place when placed in front of a rolling mill even with different mass distribution and thus the deviations can still within the production of e.g. be corrected before cutting or further processing. Furthermore, advantageously, the dough pressure in the roll area can be measured at one or more points and the rolling mill or the dough sheet plant can comprise corresponding sensors and the dough pressure can be taken into account in the control.

Furthermore, when using the weighing device 10 within a Teigbandanlage the weighing device 10 may be arranged according to a longitudinal cutting unit and detected depending on the load of the load cells 2, how many pieces of dough or dough strands were cut and so an automatic row recognition can be realized.

As shown in the described embodiments, a single dough sheet, which extends along the entire width of the weighing device 10 and all weighing cells 2 or a defined number of weighing cells 2 applied, are measured, and the mass distribution or the mass flow of this dough sheet detected become. Alternatively, however, a plurality of dough bands or dough strands can be guided in parallel over the weighing cells 2 or in each case over a part of the weighing cells 2 and thus deviations between dough strands or the mass flow of the dough strips or dough strands are detected.

Alternatively, or in addition to the above uses, the weighing device 10 may also be used to determine the cut length within the length of the dough strip. Thus, for example, in a cross-cutting unit with adjustable blades or a cutting robot, the cutting length can be changed based on the mass distribution.

Furthermore, it is provided that the mass flow of the dough is determined by the weighing device or within the dough belt system by integrating the measured values obtained from the weighing cells 2 with the belt speed of the dough belt moving over the weighing cells 2 and the masses passing through the weighing cells 2. Depending on the mass flow, the transport speed of the conveyor belts 4 or the circulation speed of calibration rollers can then be adjusted and a targeted mass flow can thus be generated downstream of the weighing device 10. Furthermore, the mass distribution along the width of the dough strip can be adjusted or changed by upsetting the dough sheet and / or changing the belt speed after the weighing device 10.

Furthermore, individual pieces of dough with a defined width and length of the device can be fed analogously to endless sections and the mass distribution or the mass of these pieces of dough can be determined.

Furthermore, it is possible to use the band weighing device as a basis for the adjustment and control of the rolls.

A further advantageous application of the weighing device 10 provides that the weighing cells 2 and / or the transport rollers 3 connected to the weighing cells 2 or the sliding supports 16 are conveyed over the transport plane of the dough sheet, e.g. beyond the imaginary plane of the two conveyor belts 4a, 4b, protrude. The dough band is then guided over a predetermined range over the load cells 2 and / or transport rollers 3 and / or sliding supports 16 so that the dough band at least partially wraps around the weighing cells 2 and / or the transport rollers 3 and / or the sliding supports 16. Based on the change in the measured measured values of the weighing cells 2, the tension of the dough sheet can then be determined. Thus, for example, the dough strip can be guided over a quarter of the circumference of the transport rollers 3 and based on the change in the slack between the transport roller 3 and the next conveyor belt 4 and the associated change in the mass measured by the load cells 2 by comparison with a reference model, the tension of the dough strip be recorded.

Alternatively, instead of the dough band, other bands, such as cloth, paper or steel bands of the device can be supplied and the illustrated weighing device 10 are adapted to the requirements of these bands. Likewise, the method according to the invention can also be used for such bands.

For calibrating the weighing cells 2 or the weighing device 10, a defined calibration band can be conveyed over them and the resulting measured values used for setting the weighing cells 2 and the evaluation unit 7.
